BOTTLE-SEAL.

Specification of Letters Patent.

Patented July 31, 1906.

Application filed April 20, 1906. Serial No. 312,884:-

To an whom it may concern.-

Be it known that I, STANISLAS MATHIEU, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Bottle-Seal, of which thefollowing is a specification.

My invention relates to a device for sealing bottles, jars, and otherreceptacles in such a manner that they cannot be unsealed except bymutilating them to such a degree that the fact of their having beenunsealed will be readily observable and cannot be concealed.

It has heretofore been proposed to provide bottles with a plunger forcedoutwardly from the neck of the bottle into a cap extending over theneck; but this device, although exhibiting a principle theoretically ofvalue, necessitates the use of an additional element.

It is the principal object of my invention to secure all the goodresults of such constructions Without the use of the additional elementand by such simple and inexpensive means that the device will have awide range of utility and to guard against the presence of projectingbroken edges.

Reference is to be had to the accompanying drawings, in which Figure 1is a side elevation of a receptacle provided with a seal which comeswithin the scope of my invention. Fig. 2 is a central sectional view ofanother receptacle provided with the same seal. Fig. 3 is a sideelevation of the stopper and plunger shown in Fig. 2. Fig. 4 is aperspective view of the packing or cork which I have indicated in Fig.2.

In the form which I have illustrated the neck of the bottle or otherreceptacle is provided with a shoulder a, on which rests a cylindricalcork or packing b.

The stopper 0, which is intended to enter the neck, is provided with areduced portion 0 and a shoulder '0 adapted to fit the packing 6. Thestopper is also provided with a head 0 which when the stopper is inproper position extends over the top of the mouth of the bottle andcovers the same.

While I have described a particular form of cork, neck, and packing, Iwish it to be distinctly understood that my invention is applicable tomany other forms of these elements, and, in fact, can be usedpractically with all types of receptacle-closures in which the stopperpasses into the neck of thereceptacle. Extending part way through thestopper is a cavity (1. In this cavity is mounted a spring 6 and aplunger f.

Extending outwardly from the inner surface of the neck of the bottle isa radial cavity g. This cavity is provided at some point accessible fromthe outside with a thin wall, preferably of the material of which thereceptacle is formed, and designated by the character g. This cavity isof sufficient depth to receive the end of the plunger f and is intendedto hold it when the stopper is in position, as shown in Fig. 2.

When it is desired to remove the stopper, the thin wall is fractured byknocking off a projection h, extending beyond the thin wall, whichaflords means whereby the thin wall may be readily broken. It is alsoprovided with a circular cavity 1c, so that when the thin wall is brokenthe projecting sharp points will lie within the outer surface of thebottleneck and not be in a position to injure ersons using the bottle.This avoids one o the great disadvantages of certain bottle-seals whichhave been proposed.

The manner of inserting the stopper after the bottle is filled withliquid for the first time is very simple.

The plunger, as shown in Fig. 2, is placed in position with the springinside the cavity and is pressed inwardly by any desired means until thestopper can be inserted into the neck of the bottle. Then the stopper isturned until the plunger enters the cavity 9, and, obviously, the bottleis sealed and cannot be opened unless the seal is broken.

While I have illustrated and described one form in which I at presentrefer to embody my invention, I am aware t at many modifications may bemade Within the scope of the invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. The combination of a receptacle having a neck provided with adepression in its inner surface extending substantially to the outersurface of the neck, and having a thick wall at the end of thedepression and a thin wall surrounding the end of the depression, theouter surface of the neck being provided with an annular circular grooveor cavity surrounding the depression, and a stopper having aspring-pressed plunger adapted to enter said depression.

2. A receptacle having a neck provided with an interior radialdepression, the end of i In testimony whereof Iha ve hereunto set saiddepression being surrounded by a thin my hand in the presence of twosubscribing fragile Wall and by an annular groove de- Witnesses.

pressed inwardly from the outer surface of STAN ISLAS MATHIEU. 5 theneck to permit the outer Wall of the de- Witnesses:
